This is a shortened but still lengthy version of an Indian doctoral thesis. It concentrates on one village and one type of stove, providing extensive testing and good reporting on especially the amount of fuel consumed (mostly for water boiling) and the time taken to acquire it. <o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal> 3. The main new feature is on using a simple low cost means of getting swirl and thereby better gas mixing. The addition is called a TT - twisted tape. Seems like it is adding 5% to stove efficiencies (which started in the 20-25% range), otherwise no changes to these tradition stoves. The paper provides a good review of almost everything else about simple stoves, including comments on WBTs. The TTs should be applicable to Rockets, TLUDs, etc.<o:p></o:p></p></div><div><p class=MsoNormal><o:p> </o:p></p></div><div><p class=MsoNormal> 4. I have lost how I came to read it.
